Rubus strigosus

Rubus strigosus, the American red raspberry or American raspberry, is a species of Rubus native to much of North America. It was often treated as a variety or subspecies of the closely related Eurasian Rubus idaeus (red raspberry or European red raspberry), but is now more commonly treated as a distinct species. Many of the commercial raspberry cultivars grown for their fruit derive from hybrids between R. strigosus and R. idaeus; see Raspberry for more details.
